6.9 DVD Serial Data Interface

This interface connects to the data port of low cost

DVD loaders using a 4-wire serial interface. In this

case, control for the loader will typically be done

using the 2-wire serial interface master. The ATA-

PI/IO channel pins are then free to be used for a

second DVD loader, a general purpose ATAPI, or

as GPIOs.
